  • Baling material and baling device for making baled articles
    Patent number: 4917008
    Abstract: An elongated strip of baling material has opposite longitudinal edges, each of which includes an elastic element extending in the longitudinal direction of the strip. The width of the strip is greater than the length of the bale so that when the strip is wrapped around a bale, the opposite longitudinal edges of the strip extend radially inwardly to cover the outer peripheral portions of each of the end faces of the bale. The strip is held in place by the elastic elements in the longitudinal edges of the strip to protect the peripheral portions of the end faces of the bale.
